Quote History Quoted:
Good lube.
5.56 pressure ammo.
That's about it, outside of actually shooting in intended climate as the ultimate test.
Is your dissy upper a true dissipator, or faux dissipator? A true dissipator will have a tougher time with lower power ammo and/or heavier buffers and/or heavier recoil springs in really cold conditions.
ETA: or do you mean cosmetically?

Both, but mostly functionally.
What lube is best for cold weather? I have a lot of CLP but I can't remember what temperature that is good til.
The upper is from PSA so I think it's a mid length gas system. Going to use an extended latch charging handle, PSA premium BCG, extended take down pins and a magpul trigger guard.
Most of my ammo pile is Wolf Gold, I think that was pretty close to 5.56 specs. Otherwise I'll use some PPU 62gr.
